Boeing appears to be investing in the employees, at least in their huge Charleston facility.

Boeing Co is expected to receive final approval on Thursday to build what could be a Silicon Valley-style corporate campus as part of a major expansion of its factory in South Carolina.

Boeing has asked officials to rezone 466 acres of newly acquired land for use as an “Aerospace Campus,” with dining and other consumer conveniences more familiar to employees of Amazon.com Inc or Google Inc than airplane factory workers.

Boeing, which tends to be guarded about any future expansion, said there no immediate plans to start erecting the new services, but it is not ruling them out.

The conceptual plan shows the “maximum utilization” of the site “as potential future business needs might dictate,” spokeswoman Candy Eslinger said.

The new zoning would enable Boeing to include restaurants, coffee shops, cafes, dry cleaners, office supply stores, travel agencies, barber shops, newsstands, convenience stores, and child care, health and postal facilities, according to plans filed with the city of North Charleston.
